The sentences using "resilient" correctly are:
- The most resilient bacteria can withstand even radiation.
- With over 20 films, she has become one of the world's most resilient actresses.
- The resilient politician steadfastly refused to give in to corruption.
The sentence that is incorrect is:
- Antarctica experiences some of the most resilient weather in the world.
In this case, "resilient" is not the appropriate term to describe weather. "Resilient" generally refers to the ability to recover from difficulties or the capacity to withstand stress, making it suitable in the context of bacteria, people, and politicians but not weather.
